Build a browser agent
Build an autonomous browser agent that navigates the web, extracts data, and completes tasks using Stagehand and Browserbase cloud browsers.
Get started building browser agents on the Browserbase platform
Build a fully autonomous browser agent using Stagehand Agent running on Browserbase cloud browsers. Give the agent a natural language instruction and it plans, navigates, interacts with pages, and returns structured results — no manual scripting or selector maintenance required.
Browserbase handles the cloud browser infrastructure: session management, anti-bot stealth mode, proxy rotation, and CAPTCHA solving. You focus on defining the task. The agent handles everything else.
Perfect as a starting point for building AI-powered web automation, research agents, data extraction pipelines, and multi-step workflow bots.
Steps
Use Browserbase Search to find the URLs you want to explore
Then use Browserbase Fetch to extract the content of the page
Initialize a Stagehand session connected to a Browserbase browser
Create a Stagehand Agent with a system prompt describing the task
Give the agent a natural language instruction (e.g., search for a topic and summarize results)
The agent autonomously navigates pages, clicks, types, and extracts data
Returns structured results after completing all steps
